In recent years, the intersection between physical exercise and its effects on substance use disorders has garnered significant interest within the scientific community. A new study delves into this relationship, exploring how regular physical activity might influence the severity of dependence among individuals who use illicit substances. The research, published in the  Journal of Psychoactive Drugs , provides evidence that engaging in frequent exercise may be associated with lower levels of dependency on various drugs. Substance use disorders represent a significant challenge to public health systems worldwide, characterized by high rates of relapse post-treatment. Traditional approaches to addiction treatment have often focused on psychological and pharmacological interventions, yet emerging evidence suggests that supplementary strategies, such as exercise, could offer additional benefits. The rationale behind this study is rooted in the complex interplay between physical activi...

Summary:   A new study reveals a strong link between daytime physical activity and improved sleep quality among both children and adults. Analyzing the daily routines of over 2500 participants, the research highlights how higher levels of moderate to vigorous physical activity correlate with fewer sleep disturbances, less daytime tiredness, and overall better sleep quality. Unlike common sleep improvement tactics that focus on pre-bedtime routines, this study emphasizes the integral role of daytime activities, especially exercise, in enhancing sleep. The findings suggest that incorporating more physical activity into our daily lives could be a simple yet effective strategy for achieving better sleep and, by extension, improving overall health and wellbeing. Key Facts: Physical Activity Boosts Sleep Quality : Both children and adults who engage in higher levels of physical activity experience better sleep outcomes. Daytime Decisions Affect Nighttime Rest : The study underscores the ...

  Doctors call physical exercise a “polypill,” because it can prevent and treat many of the chronic diseases that are associated with aging. A new study of muscle fibers from mice and humans shows how exercise affects gene expression. The exercise-induced changes “reprogram” the epigenetic expression of the fibers to a more youthful state. The findings could provide leads for the development of drugs to mimic these benefits in people who are unable to exercise. Research shows that people who exercise regularly not only strengthen their muscles but also improve their overall health, regardless of how late in life they start. For example, recent studies have found that exercise reduces the risk of  cardiovascular disease , as well as  Alzheimer’s and Parkinson’s  in older people. Conversely, reductions in muscle mass and strength are associated with lower quality of life and  higher mortality from all causes . As a result of its proven ability to prevent and treat...

Scientists are intrigued by a drug that appears to imbue mice with the benefits of exercise without actually getting physical activity — but as you'd imagine, there are caveats, so don't throw out your workout clothes just yet. As a  University of Florida press release  about the new research declares, the newly developed compound SLU-PP-332 led obese mice to lose weight by apparently convincing their bodies to go into marathon training mode, leading to a faster metabolism and more energy and endurance, and all without actually exercising. "This compound is basically telling skeletal muscle to make the same changes you see during endurance training," Thomas Burris, a UF pharmacy professor who led the research, said in the school's press release. SLU-PP-332 purports to achieve this by targeting what are known as EFF proteins that activate the body's most "energy-gobbling" tissues, such as the brain, the heart, and other muscles. ERRs are naturally rel...

You can boost your speed by taking 100 mg of the co-enzyme  Q10  every day. To be more precise: your ability to perform fast and explosive movements in quick succession will increase slightly, according to a human study done by Turkish sports scientists at Selcuk University and  published in the Journal of Strength and Conditioning Research. You can boost your speed by taking 100 mg of the co-enzyme  Q10  every day. To be more precise: your ability to perform fast and explosive movements in quick succession will increase slightly, according to a human study done by Turkish sports scientists at Selcuk University and  published in the Journal of Strength and Conditioning Research. The results of these studies are mixed. Many show no effect, some show a little effect.  A 2008 study  showed that if you get people to cycle to the point of exhaustion Q10 supplementation will improve their endurance capacity a little. Endurance athletes who have been tra...
